摘要： Embodiments of the present invention provide systems and methods for converting a high-resolution image to a lower-resolution image with reduced visible errors. These systems and methods comprise a sub-pixel sampling simulation performed on a high-resolution image to determine an error introduced into the high-resolution image as a result of sub-pixel sampling. This error may be isolated from the high-resolution image to create an error image which may be modified with a visual model to remove invisible errors thereby creating a visible error image. The visual error image may then be combined with said high-resolution image to create a compensated image that will substantially cancel the error introduced as a result of subsequent sub-pixel sampling when the sub-pixel sampling occurs.

摘要： A technique for reducing noise in pixel images includes shrinking initial image data, and processing the shrunken image with known segmentation-based filtering techniques which identify and differentially process structures within the image. After processing, the shrunken image is enlarged to the dimensions of the initial data, subsequently processed if necessary and the final image is displayed or analyzed. The resulting technique is versatile and provides greatly improved computational efficiency while maintaining image quality and robustness.

摘要： A system and a method solve the estimation problem of finding reflectance R and illumination L. The system and method to solve a functional of the unknown illumination L such that a minimum of the functional is assumed to yield a good estimate of the illumination L. Having a good estimate of the illumination L implies a good estimate of the reflectance R. The functional uses a variational framework to express requirements for the optimal solution. The requirements include: 1) that the illumination L is spatially smooth; 2) that the reflectance values are in the interval null0,1null nullthus, when decomposing the image S, the solution should satisfy the constraint L>S; 3) that among all possible solutions, the estimate of the illumination L should be as close as possible to the image S, so that the contrast of the obtained R is maximal; and 4) that the reflectance R complies with typical natural image behavior (e.g., the reflectance is piece-wise smooth).

摘要： In an image processing device which carries out processing for detecting and correcting defective portions of an image, it is possible to pre-emptively prevent the defective portion detecting and correcting processing from causing a deterioration in image quality or an excessive processing requiring time requirement. In cases in which a film type of a photographic film on which the image is recorded is a film type known to have a characteristic that an IR image is also formed at a time of image exposure and recording, and in cases in which a density distribution width of IR data is a predetermined value or more, defect detection-correction processing is cancelled. Further, in cases in which a non-image region is included in the image, either defect detection-correction is carried out only on regions other than the non-image region, or defective portion detection-correction is cancelled.

摘要： Method of and apparatus for registering a single dimensional image to a two dimensional image, and for generating spectral two dimensional images, as practiced in aerial imagery. Raw data or primary images are acquired from a subject of interest and are passed through a camera type aperture and divided by passing the light beam through a beam splitter. One beam is recorded digitally as two dimensional images containing at least three recognizable geometric reference points. The second beam is passed through a slit to form single dimensional images, which are then preferably diffracted to produce plural spectral single dimensional images. The spectral single dimensional images are recorded digitally in a manner enabling each single dimensional image to be linked to its corresponding two dimensional reference image. The beam splitter and slit device may be replaced by a selectively reflective beam splitter which accomplishes the function of both deleted components. Spectral two dimensional images may be reconstituted from the single dimensional digital record by manipulating the data to position each single dimensional image appropriately within an array. Proper location of each single dimensional image is accomplished by positioning it according to its relation to the geometric reference points. Thus a plurality of two dimensional images, each corresponding to one band of the spectrum, can be reconstituted for each original reference image.

摘要： A first signal and a second signal are obtained using a first and second image sensors, respectively. The first signal and the second signal are converted from analog to digital form. The first signal and the second signal are then averaged to improve the signal to noise ratio of the resulting signal. The first signal may be obtained using a channel corresponding to a first channel. The second signal may be obtained using a channel corresponding to a second channel. Further, a third signal may also be obtained using a channel corresponding to a third channel. Then, the first, second, and third signals may be averaged to generate an averaged signal.
